Order of Operations:
\To simplify the expression follow the order of operations: (PEMDAS)
\1. Evaluate the expressions inside the Parenthesis/Brackets (P).
\2. Evaluate Powers/Exponents (E).
\3. Multiply and/or Divide in order from left to right (MD).
\4. Add and/or Subtract in order from left to right (AS). \ \
\A simple technique for remembering the order of operations is turned into phrase
\"Please Excuse My Dear Aunty Sally".
\
The expression is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=434c8a1a056458e88d0ead83c63867b2.png\")

)
First operation is Multiplication.

)
Since numerator is zero the expression value becomes zero.
